I sell a lot of items on ebay. I haven't sold anything VMK yet and don't plan to. My understanding of PayPal transactions is that even shipping to a confirmed address can be a problem if the buyer displutes the charges. And there are other reasons for disputing charges than claiming they didn't receive the item. For example, the buyer can dispute the charges if the item doesn't match what was described in the listing. I saw a case on some court tv show where an item was sold "as is" but the ebay description had indicated it was made of one type of metal when it was actually made of a different type of metal. The judge ruled in favor of the buyer.
I know of one case where a person shipped an expensive item to a confirmed PayPal address and the buyer disputed the charges, I think they claimed they didn't receive the item. The seller had proof of delivery but PayPal still removed the funds from the seller's PayPal account. My understanding is they didn't withdraw the money from the seller's bank account, instead the seller had a huge negative balance on their PayPal account. I don't know if or how the case was ever resolved. This was a few years ago and the last I heard, the buyer still had the item and their money and PayPal wasn't helping the seller at all.
